I recently got a 20GB 4th gen iPod b/c my 10GB iPod was overfilled! (I have about 17GB of songs now). The battery life of my 1st Gen 10GB iPod also dropped to about a few minutes. It works fine when plugged in but is worthless when it is unplugged. My dad was wanting to buy my old iPod from me. So I was wonderring 2 things, 1) how much and where would you reccomend getting a new battery from? 2) what would be a reasonable price to sell it for? remember im selling it to my dad so i don't want to rip him off, and at the same time he doesnt want me to give it to him for free b/c he wants to help 'support' my college drinking habits, er i mean laundry and food. Thanks for your input!!
